<p class="MsoNormal">I don’t see any reason why that wouldn’t work but maybe there is something weird going on with the javascript session object where it isn’t getting/setting the exported variables from the session when you are doing the bridge? Have you
tried making a new session object and setting your variables for that session object instead of doing a session.execute? I found something like this on the Wiki that you might be able to do, small example below.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span style="font-family:"Droid Sans Mono";color:#333333">var anotherSession = new Session(session,
</span><span style="font-family:"Droid Sans Mono"">'{ignore_early_media=true}user/1003@' + $pbx_domain</span><span style="font-family:"Droid Sans Mono";color:#333333">);<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Droid Sans Mono";color:#333333">anotherSession.execute(‘set’,diversionHeader);<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Droid Sans Mono";color:#333333">bridge(session, anotherSession);<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-family:"Droid Sans Mono";color:#333333">anotherSession.hangup();</span><span style="font-family:"Droid Sans Mono""><o:p></o:p></span></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Like I said earlier I am a bit rusty on the Javascript side, (no idea if bridge blocks or if you have to do a loop) but I know that would work on the LUA side which is where I am more familiar. I know Javascript examples are a little light
on the wiki but you might be able to get the gist of what is going on in the LUA side and then mimic that in Javascript.

<div>
<p class="MsoNormal">Below is a bit more code to fill in the gaps. I'm passing the destination_number from the XML as a third argument. When I test out the code below, the console_log does in fact print out a "correct" Diversion header line. If I use the
exact same Diversion header, set in my XML dialplan, it shows up in the SIP packet and the VOP software reads it. When I set it using session.execute in javascript, then no Diversion header, even an incorrect one, gets added to the SIP packet. <o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I don't think it is in the variable substitution or anything like that. I've also tried not passing a variable to session.execute and just putting the string in the command, as well as just hard coding a test number. In all cases, no
Diversion header ever shows up. Either I'm not setting it right for javascript or there is something different about setting it in Javascript vs XML that I haven't figured out.<o:p></o:p></p>

declare that specifically equal to the value you passed in via args and thus javascript does you a solid and makes the whole string undefined which sets the sip_h_Diversion to null which is why it isn’t exporting. Maybe try argv[3] or argv[2] (console them
out I am not sure which one it’ll be) instead of $destination_number in your concatenation?
